Beit knownthat I, EDWARD and State New York, haveinvented certain newanduseful Improvements in Dispensing- Pumps and Mixers, of whichtheiollowing a specification.'

' and especial This invention relates to apparatus for'dispensingbeverages, such as usedfwith sodaf VVfountains andr the. "likeff Thedevice ises-v "f pecially adapted for'use with a' compara. tively thinbeverage such as milk,' especially f milk that contains aconsiderableportion of` cream, tha t requires toV be agitatedf before fit is pumpedjloutgsofthat the millrjandcreamf will be uniformly mixedvin ltl1 e container, ly at that Vpart .from which it is delivered..

One vobj ect off 1the present 'invent ion is gto j providev an improvedormofpump purpose, thatwill be simple .in 'it's t o ns't'ruc- Vtion andoperation, so that thepartszengaged can bereadilvtaken apart forf] 1fppasses andis guidedg A coil spring 24 sur- A furtherpbje'ctv of l theinvention lis' to by the .milk
